BBC bias quantified

Thanks to Craig, a regular commenter at Biased BBC we have some analysis of BBC interviewing bias. Craig listened to or watched 81 interviews between 2 June and 21 June and has tabulated the findings. here's a summary of his results:

Six of the highest interruption coefficients relate to interviews with Conservative politicians. The highest was Andrew Neil's interview with Lib Dem Jo Swinson and the highest Labour interview was with Andy Burnham!
Thirteen of the lowest sixteen interruption coefficients relate to interviews with Labour politicians, the other three were Lib Dems.

An interesting exercise would be to look at the degree of bias shown by individual interviewers. Unfortunately only Andrew Neill has enough interviews with members of each of the three main parties in this period to make the analysis workable, as more data comes in this I feel may be the most interesting figure.
Andrew Neill - highest QI and IC in interviews with Jeremy Hunt (Conservative) and Jo Swinson (Lib Dem). Conservative ave coeff = 3.8, Labour ave coeff = 2.7, Lib Dem ave coeff = 3.1.

Conclusions?
More data is required before any conclusions can be drawn but this looks like being a seriously useful piece of analysis.
